Zusammenfassung:	The rotor (4) for an electric machine (1) comprises a shaft (6), a spider (7) on the shaft (6), a laminated drum (8) on the spider (7). The spider (7) has a plurality of apart elements (13) defining ducts (14) between each other. The laminated drum (8) has a plurality of cooling channels (17) connected to the ducts (14). The rotor (4) also has throttle elements (25) associated to at least one duct (14) and/or cooling channel (17). Le rotor (4) dune machine électrique (1) comprend un arbre (6), une étoile (7) sur larbre (6) et un tambour laminé (8) sur létoile (7). Létoile (7) comprend plusieurs éléments séparés (13) définissant des conduits (14) entre eux. Le tambour laminé (8) comprend plusieurs canaux de refroidissement (17) raccordés aux conduits (14). De plus, le rotor (4) comporte des éléments de poussée (25) associés à au moins un conduit (14) ou canal de refroidissement (17).
